Send file from one endpoint to another in VB.NET - vb.net

Question

I need to send a file that I receive in 'testFile1' to 'testFile2'. I don't know if the stream I am creating is the right way to do it or if I have to retrieve the file on 'testFile2' in another way. Any help?
<HttpPost>
<Route("testFile1")>
Function postTestFile1() As IHttpActionResult
Try
Dim files = HttpContext.Current.Request.Files
If files.Count = 0 Then Throw New Exception("No file")
Dim file = files(0)
Dim req As HttpWebRequest = WebRequest.Create("http://localhost:9000/api/test/testFile2")
req.Method = "POST"
req.ContentType = "multipart/form-data"
req.ContentLength = file.ContentLength
Dim stream = req.GetRequestStream
Dim fileData As Byte()
Using BinaryReader As New BinaryReader(file.InputStream, Encoding.UTF8)
fileData = BinaryReader.ReadBytes(file.ContentLength)
End Using
stream.Write(fileData, 0, fileData.Length)
Dim response As WebResponse = req.GetResponse
Catch ex As Exception
Return InternalServerError()
End Try
End Function
<HttpPost>
<Route("testFile2")>
Function postTestFile2() As IHttpActionResult
Try
Dim files = HttpContext.Current.Request.Files
Dim requestStream = HttpContext.Current.Request.InputStream
If files.Count = 0 Then Throw New Exception("No file")
Dim file = files(0)
'Do the necessary with the file
Return Ok()
Catch ex As Exception
Return InternalServerError()
End Try
End Function
